`yum_globalconfig`

This renders a template with global yum configuration parameters. The default recipe uses it to render /etc/yum.conf. It is flexible enough to be used in other scenarios, such as building RPMs in isolation by modifying installroot.

Properties

yum_globalconfig can take most of the same parameters as a yum_repository, plus more, too numerous to describe here. Below are a few of the more commonly used ones. For a complete list, please consult the yum.conf man page (opens in a new tab)

cachedir - Directory where yum should store its cache and db files. The default is '/var/cache/yum'.
keepcache - Either true or false. Determines whether or not yum keeps the cache of headers and packages after successful installation. Default is false
debuglevel - Debug message output level. Practical range is 0-10. Default is '2'.
exclude - List of packages to exclude from updates or installs. This should be a space separated list. Shell globs using wildcards (eg. * and ?) are allowed.
install_weak_deps - Either true or false. When this option is set to true and a new package is about to be installed, all packages linked by a weak dependency relation (i.e., Recommends or Supplements flags) with this package will be pulled into the transaction. Unspecified by default; DNF's default is true.
installonlypkgs = List of package provides that should only ever be installed, never updated. Kernels in particular fall into this category. Defaults to kernel, kernel-bigmem, kernel-enterprise, kernel-smp, kernel-debug, kernel-unsupported, kernel-source, kernel-devel, kernel-PAE, kernel-PAE-debug.
logfile - Full directory and file name for where yum should write its log file.
exactarch - Either true or false. Set to true to make 'yum update' only update the architectures of packages that you have installed. ie: with this enabled yum will not install an i686 package to update an x86_64 package. Default is true
gpgcheck - Either true or false. This tells yum whether or not it should perform a GPG signature check on the packages gotten from this repository.

Example

yum_globalconfig '/my/chroot/etc/yum.conf' do
  cachedir '/my/chroot/etc/yum.conf'
  keepcache 'yes'
  debuglevel '2'
  installroot '/my/chroot'
  action :create
end
